System.Text.RegularExpressions Namespace

Provides regular expression functionality that may be used from any platform or language that runs within .NET. In addition to the types contained in this namespace, the RegexStringValidator class enables you to determine whether a particular string conforms to a regular expression pattern.

Classes

Capture

Represents the results from a single successful subexpression capture.

CaptureCollection

Represents the set of captures made by a single capturing group. The collection is immutable (read-only) and has no public constructor.

GeneratedRegexAttribute

Instructs the System.Text.RegularExpressions source generator to generate an implementation of the specified regular expression.

Group

Represents the results from a single capturing group.

GroupCollection

Returns the set of captured groups in a single match. The collection is immutable (read-only) and has no public constructor.

Match

Represents the results from a single regular expression match.

MatchCollection

Represents the set of successful matches found by iteratively applying a regular expression pattern to the input string. The collection is immutable (read-only) and has no public constructor. The Matches(String) method returns a MatchCollection object.

Regex

Represents an immutable regular expression.

RegexCompilationInfo

Provides information about a regular expression that is used to compile a regular expression to a stand-alone assembly.

RegexMatchTimeoutException

The exception that is thrown when the execution time of a regular expression pattern-matching method exceeds its time-out interval.

RegexParseException

An exception as a result of a parse error in a regular expression, with detailed information in the Error and Offset properties.

RegexRunner

The RegexRunner class is the base class for compiled regular expressions.

RegexRunnerFactory

Creates a RegexRunner class for a compiled regular expression.

Structs

Regex.ValueMatchEnumerator

Represents an enumerator containing the set of successful matches found by iteratively applying a regular expression pattern to the input span.

Regex.ValueSplitEnumerator

Represents an enumerator containing the set of splits around successful matches found by iteratively applying a regular expression pattern to the input span.

ValueMatch

Represents the results from a single regular expression match.

Enums

RegexOptions

Provides enumerated values to use to set regular expression options.

RegexParseError

Specifies the detailed underlying reason why a RegexParseException is thrown when a regular expression contains a parsing error.

Delegates

MatchEvaluator

Represents the method that is called each time a regular expression match is found during a Replace method operation.
